ASHEVILLE, N.C. (828newsNOW) — Widespread power outages stretched into Monday across the mountains as dangerously cold temperatures and strong winds moved in behind an ice storm that left roads slick and utilities strained.

At 6 a.m., the temperature in Asheville was 21 degrees, with wind chills making it feel closer to 1 degree, and snow was falling in places. Forecasters said the cold weather is expected to continue through the week.

The National Weather Service office in Greenville-Spartanburg said secondary and untreated roads remained treacherous Monday morning as lingering sleet and ice persisted. Conditions were expected to gradually improve as skies clear and temperatures rise above freezing later in the day.

A winter weather advisory was in effect until 1 p.m. Monday, while a cold weather advisory remained in place through 10 a.m., with another round of cold weather advisories beginning at 6 p.m. and lasting into Tuesday. An extreme cold warning was issued for higher elevations above 3,500 feet in parts of the mountains from Monday evening through midday Tuesday.

Forecasters warned that gusty northwest winds of 35 to 45 mph were likely across mountain areas above 3,500 feet, potentially causing additional power outages, especially in locations that experienced significant ice accumulation from Sunday’s storm.

In Asheville, Monday’s forecast called for mostly sunny skies and a high near 26, with blustery north-northwest winds gusting up to 40 mph. Overnight lows were expected to drop to around 3 degrees, with wind chills as low as minus 4. Temperatures are forecast to slowly moderate by Tuesday, with highs near 40, before colder nighttime lows persist through the end of the week.

Local officials urged residents to remain cautious on the roads. The Asheville Police Department said crews continued salting roadways but warned that falling overnight temperatures could lead to new icy spots. The Asheville Fire Department cautioned drivers about black ice, particularly on bridges, shaded areas and during early morning hours.

As of 6 a.m. Monday, more than 37,800 customers across North Carolina and South Carolina were without power, including 351 in Buncombe County and more than 13,700 in Henderson County. Utility crews continued restoration efforts as conditions allowed.

Officials encouraged residents to stay informed through NOAA Weather Radio and local updates, limit travel when possible, and take precautions against the dangerously cold temperatures
